Hello Raph,
2 or 3 bytes a cycle should still work. Again, without the benefit of
testing, one can never be sure.

Dear All,
My bandwidth is limited and I would like to use a ADPCM operating at
24Kbits/s or maybe 16Kbits/s.
Can I use one from these one with USBAudio.sys ?
Thanks In advance
Raph

Hello Raph,
The short answer to your question is yes, the ADPCM format is
supported in USBAudio.sys though we have not had any devices to
thoroughly test it with.
Thanks,

Dear All,
I develop a USB audio device and I need to use a ADPCM data
format.
I just need to know if it is possible to use this format without
to write a custom driver (maybe just using usbaudio.sys and Ks.sys).
Which are the real datas to send from the USB chip to windows ?
Thanks in advance
Raph
